Ok. Your problem is that the class is not available until the
DescribeAction. That is when the classloader dependency is
resolved. Until that point we can't guarantee the classloader even
exists.

So you're going to need a "placeholder" DependencyItem
where you fill in the type of the property once the BeanInfo 
is resolved in DescribeAction.

This is a bit messy, and would probably be better implemented
as a "revisit" of the visitor where the extra visit does extra work
once the BeanInfo is resolved, but that is a lot more work
(in terms of making the old understand it rather than doing work twice).

For now, I would just do context.getDependencyInfo(),
iterate and update the "placeholder"s.

See above. And see where annotations and their dependencies
from AOP are resolved in the DescribeAction.
